I just bought an $800 89 Saab 900 and bought a cd service manual on Ebay. It is a (probably an illegal) copy of the Mitchell on Demand Manual and it is terrible. I can't even find a page on doing an oil change. The diagrams are terrible and it is difficult to use. I would not recommend this manual. I am trying to avoid spending $60 plus shipping on a Bentley manual, but I might have to.
Just venting.
